Serial killer Mark Nash was once questioned about the murder of an elderly Fartown woman.
Former Huddersfield man, Nash, 42, jailed this week for a gruesome double murder, was questioned in 1996 over the murder of 94-year-old Dorothy Wood at her Fartown home.
But despite Huddersfield detectives travelling to Ireland where Nash was serving time in prison for a double murder, no charges were brought.
Another man Mark Dallagher, formerly of Honoria Street in Fartown, was later convicted of Mrs Wood’s murder but saw his conviction overturned seven years later.
The ruling has meant the exact circumstances of Mrs Wood’s death have remained a mystery.
A West Yorkshire Police spokesman said: “Dorothy Wood was murdered in 1996 and, as a result of enquiries, a man was convicted of her murder and subsequently spent time in prison before the conviction was later quashed.
“Enquiries have been ongoing and various people interviewed as suspects but we are satisfied based on the current evidence available to us that none of them are responsible for Dorothy’s murder.
“Should any new evidence come to light then we would of course have a look at it to see if it can add anything to the case. This case remains open and will remain so until the killer or killers of Dorothy are brought to justice”.
Nash - a former student at All Saints High School and Bradley resident- was this week found guilty of the “cold case” murder of two women, Sylvia Sheils, 59, and Mary Callanan, 61, whose mutilated bodies were found in their sheltered accommodation in Grangegorman in Dublin.
He was already serving a double life sentence in Arbour Hill Prison, where he has been held since October 1998 for murdering two people in Ballintober, Castlerea in Roscommon and leaving Sarah Jane Doyle seriously injured in mid-August in 1997.
Ireland has no minimum tariff for jail sentences and life normally sees prisoners serve between 18 and 20 years before they can apply for parole.
But one man has already spent more than 50 years behind bars for murder.
